OILING DEVICE. I

SPECIFICATION forming part of Letters Patent N 0. 791,360, dated May 30,1905.

Application filed September 19, 1903. Serial No. 173,861.

To all whom, it may concern.-

Be it known that I, RICHARD NELSON, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles, State ofCalifornia, have invented new and useful Improvements in Oiling Devices,of which the following is a specification.

My invention relates to means to oil the axle of a running-gear; and theobject thereof is to provide simple and efiicient means to keep the axlesupplied with the necessary lubricant to prevent it from unduly heatingand to make it run easy. I accomplish these objects by the mechanismdescribed herein, and illustrated in the accompanying drawings, whichshow my device applied to a carriage-wheel, and .in which Figure 1 is aside elevation, partly in central longitudinal section, of a portion ofthe axle and hub, showing my oiling device applied thereto. Fig. 2 is anend view of a portion of the hub with the follower removed.

In the drawings, A represents the hub of a carriage-wheel of ordinaryconstruction.

B is the axle, provided with the lubricantgroove C in the top thereof,which is in communication with channel E, which runs to the outer end ofthe axle through nutDQwhich is screwed upon the end of the axle to holdthe hub in place thereon. The outer end of the hub always projectsbeyond the nut on the end of the axle and is always of metal. Thisprojecting part is interiorly threaded by threads G, in which theexternally-screwthreaded follower F works. After the wheel is securedupon the axleI fill the projecting end of the hub nearly full ofaxle-grease (not shown) and screw the follower into the end of the hub asuificient distance to force the necessary amount of grease into thelubricantchannel to properly .lubricate the wheel, the square boss 'Fproviding means to turn the same with a wrench. Thereafter when moregrease is needed it is only necessary to give the follower a partialturn to force more grease into the lubricant-channel. It will be seenthat by this construction a suflicient quantity of lubricant isavailable at all times to properly lubricate the axle and that all thatis nec- Having described my invention, whatI claim as new, and desire tosecure by Letters Patent, is v The combination with an axle having alubricating-groove therein which extends to the end of the axle therebyforming an outlet at thatpoint, of a hub mounted on the axle, a nutscrewed on the end of the axle for holding the hub thereon and throughwhich nut the lubricating-groove extends, the hub having a protrudingouter end which extends beyond the nut whereby a lubricant-chamber isformed, this protruding end of the hub internally screw-threaded, and athreaded'follower screwed into the threaded end of the hub and capableof forcing the lubricant into the groove of the axle.

In witness that I claim the foregoing I have hereunto subscribed my namethis 11th day of September, 1903. r
